It's rather hard to say, if really just "single". SQLite, as I understood, has many users; just three of them were "against", until this time.
Who knows, which of the existing features are used by how many users? Yesterday one of them wrote, that (if I properly understood) he appreciates nothing more, than "job of storage". I need many other features of sqlite, its just i see the DB's #1 job as storage. After reading your response to DRH, I think your being argumentative, disrespectful and just plain rude. Thats probably not going to get you far. Since SQLITE source code is freely available, you can always create a patch to the code for the pragma your interested in. And maintain your own version. Ken
